Cable ShiverPeaks 78065-3 9-pin Sub D (DE-9) to 25-pin (DB-25) coupling cable, 3 m

The ShiverPeaks 78065-3 coupling cable is a 3 m fixed-length D-sub connection that links a 9-pin Sub D (DE-9) connector to a 25-pin Sub D (DB-25) connector. It is intended for straightforward signal pass-through between devices that use different D-sub port counts, providing a stable physical and electrical connection for serial and parallel interfaces in mixed-equipment setups.

Advantages

The cable offers a reliable mechanical coupling between DE-9 and DB-25 D-sub interfaces with secure snap hoods for strain relief and consistent contact alignment. Its 3 m length balances reach and signal integrity for typical bench and rack installations. The fixed wiring avoids the need for adapters or rewiring and reduces connection points that can introduce intermittent faults.

Suitable for

• Connecting legacy PCs or serial devices to DB-25 peripheral ports
• Interfacing industrial controllers, modems, or instrumentation with differing D-sub pin counts
• Printer or parallel-interface conversions where a direct D-sub coupling is required
• Test benches and service work requiring a reliable, short-range D-sub link

Key specifications

• Cable length: 3.0 m
• Connector A: 9-pin Sub D (DE-9) coupling (female/mating configuration for coupling)
• Connector B: 25-pin Sub D (DB-25) plug
• Conductor count: 9 cores (fixed wiring for D-sub signal mapping)
• Hood style: snap-on strain relief hoods for secure connection
• Primary use: serial and parallel D-sub signal pass-through

How to use

Align the DE-9 coupling with the 9-pin D-sub socket on the source device and the DB-25 plug with the 25-pin socket on the target device. Engage the snap hoods or fastening screws to secure each connector and ensure proper mechanical strain relief. Use the cable at its rated length without excessive bending at the connector ends; avoid routing it near high-power mains or heavy electromagnetic interference sources to maintain signal quality.

Recommendations

For reliable operation, confirm pinout compatibility between connected devices before applying power or transmitting signals. Use in environments within normal ambient temperature ranges and avoid sharp kinks or continuous flexing at the connector transitions to prolong service life.
